The Edinburgh Citadel sits on a basalt plug which is actually a part of an extinct volcano. This debate continued into the 19th century till James Hutton proved that some rocks are fashioned by volcanic (warmth & hearth) processes and others are fashioned by sedimentation. In the southwestern United States, sedimentary, volcanic, and intrusive rocks have been metamorphosed, faulted, foliated, and folded.

He cited a number of pieces of proof to show his theory—the continents all match collectively like puzzle items, the identical rock unit or fossil may very well be discovered on either side of an ocean and related features equivalent to mountains could be discovered on continents after they had been all collectively.

Movement alongside faults can result in folding, both as a result of the faults are usually not planar or as a result of rock layers are dragged alongside, forming drag folds as slip happens along the fault. Mid-ocean ridges , high areas on the seafloor the place hydrothermal …
